There is a close relationship between the formation of nodule defects in glass products and glass kiln refractory materials. Nodules are a common defect in glass products, and the causes of their formation are varied, and the influence of refractory materials is one of the links that cannot be ignored.


First, let's discuss the basic properties and functions of glass kiln refractory materials. Glass kiln refractory materials are key materials used to withstand high temperatures and prevent erosion of molten glass during glass production. The quality of the materials directly affects the stability of glass production and product quality. If the quality of the refractory materials is poor or the selection is inappropriate, it may cause them to be corroded at high temperatures, which in turn affects the quality and performance of the glass.


During the glass production process, when the refractory materials are corroded, glass phases may seep out of their surface. These glass phases drip into the molten glass liquid. Due to the high viscosity, they will not have time to diffuse and will form nodules in the glass. In addition, if the erosion resistance of the refractory materials is insufficient, it may also cause the refractory substances in the molten glass to form deposits on the surface of the refractory materials, and these deposits may also form nodules in the subsequent production process.


In addition to the erosion of refractory materials, the quality of its masonry and the temperature system will also affect the formation of glass product nodules. If the masonry of refractory materials is not tight or there are gaps, it may cause molten glass to penetrate into the interior of the refractory materials through these gaps and form nodules. At the same time, if the temperature system is not properly controlled, such as too high or too low temperature, it may also aggravate the erosion of refractory materials and the formation of nodules.


In summary, the formation of glass product nodule defects is closely related to the refractory materials of glass kilns. In order to improve the quality and performance of glass products, we need to select high-quality refractory materials, lay reasonable masonry and strictly abide by the temperature system to reduce or eliminate the occurrence of defects such as nodules.
